HIGH

Calamares 3.1-3.2.10 - Unprotected User Data Exposure via Insecure Keyfile Permissions

Title source: llm
STIX 2.1

Description

Calamares versions 3.1 through 3.2.10 copies a LUKS encryption keyfile from /crypto_keyfile.bin (mode 0600 owned by root) to /boot within a globally readable initramfs image with insecure permissions, which allows this originally protected file to be read by any user, thereby disclosing decryption keys for LUKS containers created with Full Disk Encryption.
